1 year agoNow made with Borosilicate (Pyrex) glass!I haven’t yet bought one (but it’s next on my list). I was waiting until the flasks were confirmed to be made of borosilicate glass (e.g. Pyrex) that resists thermal expansion. If the product shipped is in fact what is shown in the photo (United Scientific FG 4980), then we’re all set! United’s website affirms the glass is borosilicate, which means they are designed to resist shattering when rapidly taken from hot to cold temperatures. Adding to my wishlist now!January 18, 2018Great serviceProduct was shipped and received quickly, and just as stated in the description.March 30, 2016December 28, 2015Value during saleI bought the 2l starter during black Friday 20% off sales. In this case, it was a great value however I don't think I'd pay full price for this item. The quantity is good, DME is solid. Good overall rating.December 26, 2015Cheap FlaskYeast starters are important but this flask is junk. My particular flask in my kit was from India. I don't know if flasks in this kit changes but this one from United is just plain crap. The glass barely touched the side of a pan and the bottom section just popped off. I knew from handling the flask it was thin but I had no idea. Gone after not even one use and with it my DME. Stick with Pyrex or qt jar. This flask is so thin it almost feels like plastic. I am surprised that Midwest even sells this flask._x000D_Tried to give it zero stars but I guess that is not an option.August 29, 2015Went CrazyPicked up the 2L Starter kit to do the Hop Lord extract kit. So, I stired up a 2L starter. It went crazy! After approximately 13-14 hrs the thing looked like it was going to Blow Out. Used WL California Ale Yeast WLP001. I am guessing I am going to need to rig up a blow out tube when I pitch this later today (9/1/14).September 1, 2014get itAs I've progressed in my brewing I've learned that a yeast starter is necessary for some beers. This is a good kit. I personally like the 2L flask because I just out it directly on my stove and boil the water for the starter in the flask. It sanitizes the flask again and removes the possibilities of any little microbes finding there way to it during transfer. Besides that the foam stopper works just fine. You don't need to get a rubber one, but I like the look of the rubber one.March 30, 2014
